\frac{8a^{3}-27}{27}
\frac{1}{27} omili.
\left(2a-3\right)\left(4a^{2}+6a+9\right)
Hisoblang: 8a^{3}-27. 8a^{3}-27 ni \left(2a\right)^{3}-3^{3} sifatida qaytadan yozish. Kublarning farqini ushbu formula bilan hisoblash mumkin: p^{3}-q^{3}=\left(p-q\right)\left(p^{2}+pq+q^{2}\right).
\frac{\left(2a-3\right)\left(4a^{2}+6a+9\right)}{27}
Toʻliq ajratilgan ifodani qaytadan yozing. Koʻphadli 4a^{2}+6a+9 faktorlanmagan, chunki unda ratsional ildizlar topilmadi.
